SKF PHS series sprockets are toothed wheels that mount on shafts and mesh with ANSI pitch chains to transmit motion and force in industrial machinery. They suit drives that call for a precise ratio and straightforward maintenance. MR Industrial Accessories supplies this line as part of its power transmission range and can help you match pitch and tooth count to your application.

Reading a PHS designation is simple. PHS marks the SKF sprocket line. The first number after the dash gives the chain pitch under the ANSI standard, so 25 means a 1/4 inch pitch. The letter B denotes a single-strand sprocket, and the final number is the tooth count. A PHS 25-1B9 therefore has 25 pitch, one strand and 9 teeth, while a PHS 25-1B16 carries 16 teeth. More teeth produce a larger pitch diameter and a lower rotation speed at the same chain speed.

These sprockets appear in food processing, bottling, material handling, agricultural machinery, earthmoving equipment and general production lines. They are common in low and medium power drives where a constant ratio and low maintenance are priorities, and they also show up in lifting equipment, conveyor belts and industrial door drives. The PHS series covers small pitches, which makes it a good fit for compact mechanisms.

Selection depends on chain pitch, tooth count, shaft diameter and the fastening method, whether keyway, set screw or taper bushing. Confirm that the material and surface treatment suit the load and operating speed. At installation, check alignment between sprocket and chain to prevent premature wear, lubricate as the manufacturer recommends and inspect chain tension at regular intervals. A clean, aligned installation helps the assembly last.

When a sprocket needs replacing, equivalents often exist across brands that follow the same pitch and tooth-count standard. Part numbers may differ, but an ANSI 25 sprocket with 9 teeth from another brand is frequently interchangeable if pitch, tooth count and bore diameter match. Verify critical dimensions before fitting. Our team can review compatibility without putting your equipment at risk.
